Check your diff rings for wear. If they’re not new, there will be a thin line
on the face of each one where the balls run. Darker line = more wear.
You can use both sides of the rings, so if one side has not been used, flip
them over. Carbide diff balls like X Factory’s #6500 are much harder than
the rings, so one set of balls should last through several sets of rings.
Many X Factory drivers prefer B Fast diff rings for smoother, longer-lasting
diffs. Take the new outdrives (AE7667 & 7668) from Bag A and on each
one put a small drop of diff lube on one part of the edge where the ring will
go (left photo). This grease does not lubricate, it merely holds the ring on
during assembly. Grease attracts dirt (bad) so use as little as possible
here. Wipe off any excess grease (right photo).

Re-install the diff balls and one diff
bearing into the diff gear. Put a small
amount of diff lube on one side of
each of the balls. We used too much
in the photo so you can see the lube.
You need surprisingly little lube, and
excess is just thrown off inside the
transmission case. Many X Factory
Team drivers use B-Fast Pro Lube.

Install the second diff bearing into the female
outdrive.
